getting creative here now..........I thought about 1/4 " flat metal plate ... bolt yo top of that cyl bore .. drill a hole in center plate ...weld a big nut on it .. then a long threaded bolt to a flat plate lying on top the piston . and just crank the screw down by hand and it should move. problem is .. the highest flat part of the dome piston is off center and wouldn't apply equal pressure to the piston. I might work though. just a thought .
